I thought the main argument against amp links is that they make it easier for Google to track you, and it takes away ad revenue from publishers. Yet the irony is with your archive link, I had to solve multiple Google ReCaptcha puzzles (which also took an entire minute of my life), and The Guardian still gets no ad revenue. I'll stick to amp links.
firefox right? there's a dns setting that causes this behavior with archive.today, I think it's encrypted DNS you need to turn off. DNS over HTTPS? something like that
